Cebrennus  spec. A

Figs 14View FIGURES 12 – 17. 12 – 13, 173View FIGURE 173

Material examined. ALGERIA: Bechar Province: 1 male (PJ 3466), Grand Erg occidental, Beni Abbes [N 30 ° 8 ' 0.01 ", W 2 ° 9 ' 59.98 ", ca. 500 m elev.], Coll. Denis, December 1949 ( MNHN).

Diagnosis. Medium-sized Sparassinae, body length of male: 10.6. Male copulatory organ similar to those of C. wagae  , C. flagellatus  spec. nov., C. aethiopicus  and C. castaneitarsis  in having a very long embolus with distal loop as long as the tegulum or larger ( Fig. 14View FIGURES 12 – 17. 12 – 13), but distinguished from C. flagellatus  spec. nov. by the absence of an additional flagellum at the embolus kink, from C. castaneitarsis  and C. flagellatus  spec. nov. by its relatively long embolus (in retrolateral view the RTA is longer than the tibia length, i.e. the ratio RTA/tibia is 1.21), from C. aethiopicus  distinctly and from C. wagae  slightly in having the embolus arising point shifted prolaterally. Chelicerae with 2 anterior and 4 posterior teeth. Margin of chelicerae close to fang base with 3 and 5 bristles, respectively.

Description. Male: PL 5.1, PW 3.9, AW 2.8, OL 5.4, OW 3.5; AME 0.40, ALE 0.29, PME 0.25, PLE 0.26, AME –AME 0.17, AME –ALE 0.13, PME –PME 0.43, PME –PLE 0.50, AME –PME 0.30, ALE –PLE 0.45, clypeus AME 0.12, clypeus ALE 0.15. Spination: Palp: 130, 0 0 0, 1000; legs (II lacking): femur I, III 323, IV 322; patella I, III –IV 000; tibia I 2024, III 2024, IV 2023; metatarsus I, III 2024, IV 3026. Ventral metatarsi I –IV with scopula in distal half, without spines or bristles distally. Measurements leg I: 25.0 (7.2, 2.3, 6.6, 7.1, 1.8).

Colouration: pale yellowish brown, without pattern.

Note. This male specimen cannot be assigned clearly to one of the known species. Its intermediate position between C. wagae  and C. castaneitarsis  and the absence of sufficient data on intraspecific variability (see introduction) makes it difficult to decide whether the male possibly belongs to an own species or not. Considering its geographic distribution (1000 km SW of type locality of C. wagae  , 640 km SSW of type locality C.

castaneitarsis  , 760 km E of locality of the female listed below; Fig. 173View FIGURE 173) and considering that no other records of the species involved are known from the region around Beni Abbes, the specimen is left unidentified until more material is available.
